As the National Park Service (NPS) enters its second century, sustainability and environmental stewardship remain a key focus. Over the last 100 years, the NPS has prioritized the preservation of this country’s natural landscapes for the enjoyment of future generations. With transportation accounting for over 30 percent of annual GHG emissions from its operations, the NPS has prioritized reducing emissions associated with its fleets by incorporating new pollution-reducing vehicle technologies into its parks. To help achieve this goal, NPS began this week operating zero-tailpipe-emission Proterra battery-electric buses in Bryce Canyon National Park and Zion Nation Park. Learn more about how battery-electric buses are helping keep America’s majestic outdoor spaces beautiful and vibrant in our latest blog post authored by Proterra CEO Ryan Popple.
